The deference between C and C++ is vast. You can do templates and meta programming in C++ that you can't in C. Similarly you can do templates and meta programming in Metal So to say all shader languages are based on C is as useful as saying they're all based on assembly. I'm not saying C++ style templates are good or bad but they're vastly more powerful than not having them and if you're using those other C based shader languages you'll end up having to do code generation in some other language to provide the same features as a C++ based shader language
